Intelligent Transportation System Over Fiber Gigabit Ethernet

Intelligent transportation case study

Application: Traffic Control Monitoring Systems
Industry: Intelligent Transportation
Region: USA

Case Study Overview

The third largest state-owned highway system in the United States is maintained by the state DOT (Department of Transportation). The state DOT planned to centralize traffic control/monitoring of highways (including roads, bridges, and tunnels) across the state’s five central TMCs (traffic management center). These TMCs serve as hubs for regional emergency response and incident management operations of traffic-related events. TMC operators will have access to real-time traffic information from DOT personnel, state police, emergency response agencies, cameras, sensors, and other tools to ensure traveler safety by notifying drivers of traffic conditions and emergency events via VMS (variable message sign) broadcasts and other public media. “Our role is to facilitate the safe and efficient travel of drivers… By coordinating fast, effective incident response and communicating traffic information to the public in a timely manner from our Traffic Management Centers, we can provide the best possible driving experience for our customer.” said the DOT Commisioner.

System Requirements & Challenges

  • Gigabit network backbone for large volumes of video data
  • NEMA TS2 compliance for network components
  • Network redundancy with secure data encryption capability
  • Network traffic management for bandwidth efficiency
  • Industrial durability to withstand severe outdoor conditions
  • Fiber interface for long distance transmission with high scalability

Moxa Solution

  • Moxa’s EDS-510A-T industrial Ethernet switches (with Moxa SFP-1G gigabit Ethernet SFP modules) were chosen to build regional gigabit ethernet backbones over fiber for each TMC, with transmissions of up to 120 km.
  • The EDS-510A-T managed switches were configured with IGMP snooping to optimize bandwidth usage and reduce network congestion.
  • Each EDS-510A-T offers secure connections with TACACS+, SNMPv3, IEEE802.1x, HTTPS, and SSH to prevent unauthorized network access, features Turbo Ring™ technology to provide provide network redundancy with recovery times of less than 50 ms (at 250-switch load), and supports topology options such as Ring Coupling to provide a backup path and ensure uninterrupted connectivity when a link fails.
  • The NPort 6450-T terminal servers feature Moxa’s Real COM mode for secure remote operation and Ethernet connectivity to existing serial devices such as vehicle loop sensors and VMS (variable message sign) equipment.
  • The EDS-510A-T switches and NPort 6450-T terminal servers can operate reliably in harsh highway operating conditions due to their wide temperature tolerance (-40 to 75°C).
